HESI A2 test Biology - Cell Reproduction Meiosis

Which of the following events occurs exclusively during prophase I of meiosis and contributes to genetic diversity in offspring?

Homologous chromosomes exchange segments in a process called crossing over.

During sexual reproduction, the zygote is formed when a male gamete fuses with a female gamete. How many chromosomes does the zygote cell contain?

2n

Which of the following is correct about the difference between sexual and asexual reproduction? 

In asexual reproduction, diploid parent cells produce diploid daughter cells. Sexual reproduction, typically involves the fusion of two haploid (n) gametes (one from each parent), which results in a diploid (2n) zygote. This zygote then develops into a diploid organism.

Which of the following mechanisms involves the division of a single cell to form cells with half of the original amount of genetic material?

Meiosis

Which of the following lists the phases of meiosis in the correct order?

Prophase I, Metaphase I, Anaphase I, Telophase I, Cytokinesis, Prophase II, Metaphase II, Anaphase II, Telophase II, Cytokinesis

How many chromosomes are in daughter cells produced by meiosis?

23

Which of the following stages of meiosis is shown below?

Interphase

“Each chromosome ends up with an identical twin called sister chromatids.”

The above process takes place in which of the following phases of meiosis?

Interphase

Which of the following is the function of meiotic cell division? 

Formation of sex cells or gametes

“Homologous chromosomes line up to the center of the cell.” 

This event occurs in which phase of meiosis?

Metaphase I

“Homologous pairs pull apart and move to opposite ends of the cell.” 

This event occurs in which of the following phases of meiosis? 

Anaphase I

“Chromosomes arrive at opposite poles of the cell and the nuclear membrane reforms.”

This event occurs in which phase of meiosis?

Telophase I

During Prophase II of meiosis, which of the following events happens?

The nuclear membrane starts to break down, and the chromosomes recondense.

Which of the following phases of meiosis II has been shown below?

Metaphase II

Which of the following is NOT a phase of meiosis?

Interphase

Which of the following statements is true about crossing over?

It increases genetic diversity.

Which of the following statements is true about crossing over?

Meiosis I involves crossing over, whereas meiosis II does not.

How many daughter cells are produced at the end of meiosis?

4

Which of the following statements is true about homologous chromosomes?

They contain the same genes but may have different alleles.

Which of the following is true about the process of meiosis?

It involves two rounds of cell division.
